Nylon-6-b-polyimide-b-nylon-6 copolymers were prepared by first synthesizing a series of imide oligomers end-capped with phenyl 4-aminobenzoate. The oligomers were then used to activate the anionic polymerization of molten โ-caprolactam. In the block copolymer syntheses, the phenyl ester groups rea
## SYNOPSIS New polyimides containing diamantane units were prepared by a conventional two-step method starting from 1,6-diaminodiamantane and aromatic dianhydrides. The intermediate poly(amic acid)s had inherent viscosities of 0.33-0.55 dL/g. These polyimides did not decompose below 400ยฐC in air
